2013-02-20add mkostemp, mkstemps, and mkostemps functions and reorganize temp internalsRich Felker-19/+2
based on patch contributed by Anthony G. Basile (blueness) some issues remain with the filename generation algorithm and other small bugs, but this patch has been sitting around long enough that I feel it's best to get it committed and then work out any remaining issues.
2011-02-19make mktemp match the historic behavior, and update functions that use itRich Felker-2/+3
the historic mktemp is supposed to blank the template string on failure, rather than returning 0. just zero the first character so that mkstemp and mkdtemp can still retry with O(1) space requirement.
2011-02-19fix major bug created from copying mkdtemp logicRich Felker-1/+1
2011-02-18major improvements to temp file name generatorRich Felker-2/+3
use current time in nanoseconds and some potentially-random (if aslr is enabled) pointer values for the initial tempfile name generation, and step via a cheap linear prng on collisions. limit the number of retry attempts to prevent denial of service attacks even if an attacker can guess the filenames.
2011-02-18reformat mkstemp like mkdtempRich Felker-7/+5
this is cleaner and makes it easy to impose a limit on the number of retries later if it seems desirable to do so.
